Claims.. (01. 45-112) This invention relates to new and useful improvements in extension tables, and more specifically to means whereby such tables may be more quickly extended when it is desired to insert 5 or remove one of the top loose leaves thereof.

In the act of removing or inserting a leaf of an extension table, it has heretofore generally required two operators, one at each end to pull the leaves apart, thereby separating the fixed 0 leaves and providing space for the insertion or removal of a loose leaf. The object of the present invention is the provision of a structure which is so designed and assembled, that one operator may quickly and easily actuate mechanisms which will automatically open the table and insert or remove one of the loose leaves, dependent upon the direction of throw of said lever.

Another object of the invention is the provision of means whereby a cabinet, adapted to receive silverware, china, table linen, salt, pepper and other condiments, is formed below. the table top. Such cabinet is provided with a bottom and two sides, two end leaves being pivotally secured to the bottom wall of the cabinet, said leaves being adapted for movement, upwardly and downwardly, to complete the box-like formation of the cabinet, by the mechanism which causes the opening and closing of the table top.

Other objects of the invention will be made apparent from the following specification, when, considered in connection with the drawings forming a part thereof.

In said drawings:

Fig. 1 is a bottom plan view of my improved extension table in closed position.

Fig. 2 is a similar view with the table shown in open position.

Fig. 3 is anenlarged, staggered sectional view on the line 3-3 of Fig. 1.

Fig. 4 is a similar view, with the table portions shown in open position.

Fig. 5 is an enlarged longitudinal section of table, all parts shown in closed position, and,

Fig. 6 is a detail perspective view of the extension leaf in raised position, the extension side leaves being vertical.

Now referring specifically to the drawings, in which like reference numerals indicate like parts throughout the several views, 10 indicates the lower side of an extensible table top which is supported upon the usual framework consisting of legs 11, side rails 12, end rails 13, and

. cross rails 14, all as clearly illustrated in Figs. 1

and 2. The top 10 is slidably mounted upon the frame and is held in position by cleats 21, 21, fastened to the underside of the top and co-acting with angle bars 22, fastened to the side rails 12.

The central compartment confined by the side '60 rails 12 and the cross rails 14 is utilized as a cabinet for the storage of silverware, condiments. table linen, and dishes, and also houses a vertically movable leaf 15 which forms the bottom of the compartment or cabinet, when in its lower position, the table top 10 serving as the top of said compartment when the table is in its closed position.

In order to automatically open the table and simultaneously raise the extension leaves to the level of the separated table portions, I have provided mechanisms which will hereinafter be described in detail.

Secured to underside of the cross rails 14, is a strap member 16 to which is pivoted, at 17, an operating lever 18. A link 19 is provided with an end pivotally secured to the inner end of the operating lever .18, the other end of said link being secured to plate 20, connected to the bottom of the table top.

With the construction as so far described, it will be readily observed that only one side of the table top would open when the operating lever 18 is moved to the right, as shown in Fig. 2 of the drawings. However, in order to open both sides of the table top simultaneously, I have provided each of the halves of said table top with rack bars 23 which are in mesh with gears 24, supported and held against lateral movement in a housing 25 secured to the side rails 12 of the framework. It is apparent that, with the assembly just described, and clearly illustrated in Fig. 1 of the drawings, any movement of one half of the top will be transferred to the other half, through the medium of the racks 23 and gears 24, thereby opening or closing the top, dependent upon the direction of throw of the operating" lever 18.

During the operation of opening or closing the table top, the leaf 15 will be simultaneously 190 raised or lowered, and, to accomplish this result I have provided means which are inter-connected with the operating lever 18, and which will now be described.

The leaf 15 is supported upon yoke members 26, mounted on the underside of the cross rails 14, in bearings 27, one end of said yokes being connected by links 28 to a toggle 29, pivoted at 30 to a member 31 secured to the side of one of the cross rails 14. An arm 32 is slidably mounted 110 pivotally secured, as at 35, to the toggle 29, the

other end of which is connected to the operating lever 18 through a cam slotted plate 36, carried by the said operating lever 18, and a link 37, one

end of which has pin engagement with the cam slot in the plate 36.

To prevent the leaf 15 from being displaced, and for insuring its upward and downward movement, I have secured members 38 to the underside of the said leaf, said members passing over the yokes 26.

As a means for locking the table in open or closed position, a locking bar 39 is secured to one of the side rails 12, said bar passing beneath the operating lever. Pockets 40 are formed near the ends of the bar 39, into which the operating lever will drop when in either of its positions, thereby locking the lever against accidental movement. To unlock the lever it merely necessitates a lifting movement out of its pocket;

The leaf 15'is provided with hinged end pieces,

' or extensions 41 which, when the leaf is raised to a level with the table top, are manually foldable over to elongate such leaf to an extent equal to that of the entire width of the table top 10. When 'the leaf is in its lower position said extensions are folded up and lie against the inner side of the rails 12. As the operating lever 18 is swung it causes a vertical movement of the leaf 15 and, together with the rails 14 and the extensions 41, completes the cabinet.

From the foregoing it will be observed that I have provided an extension table which may be easily shifted to open or closed position by a throw ofthe operating lever, and that the said lever 'also simultaneously'actuates certain other mechanisms which complete the formation-of the desired cabinet below the table top.

[Modifications of the structure herein described may be suggested to those skilled in the art, but my invention comprehends all embodiments falling fairly within the scope of the appended claims.

I claim:-

1. In a table, separable top sections, a supporting frame for the top sections including side rails, cross rails extending between the said side rails,

a sectional leaf positioned intermediate the separable top sections and supported for vertical movement between the cross rails, a lever, a plurality of links connecting one of the top sections to the lever, and meansconnected to'said lever for moving the sectional leafsubsequent to the movement of the separable top sections.

2. In a table, separable top sections, a supporting frame for the top sections including parallel side rails, spaced parallel cross rails extending between the side rails, a leaf positioned between the separable top sections and having vertically swinging-extremities, pivoted hangers supporting the central leaf, means for operating the separable top sections, and link mechanism, connecting the operating mechanism for the top sections with the pivoted hangers, to cause a swinging movement of the latter upon separation of the top sections.

-3. The substance of claim'2, in that the hinged extremities of the central leaf engage the side rails forming the 'supportingframe for the top sections.

4. The substance of claim 2, in that the vertically movable central leaf, when in its lowered position, forms a bottom for a receptacle, further defined by the side rails and the hinged leaf extremities.

5. In a table, separable top sections, a supporting frame for the top sections including side rails, parallel spaced cross rails extending between said side rails, a central'leaf vertically movable between the cross rails and having hinged extremities 'engaging'theinner faces of the side rails when in lowered position,'and means for operating the top sections and subsequently effecting the movement of the central leaf.
